Invalid PM Error

[Tempts]

So since the new theme has been put out, I've been facing this problem. 

What happens is whenever I click on my alerts, and attempt to view a PM through the alert, I receive a page sating "Invalid PM" 

I know it's not a huge problem, but it gets annoying when you're so used to being able to just click once.

Already been suggested I think. Still, it's a small problem. I never really pay attention to my alerts anyway.

Yeah this has been happening to me too, on some occasions it also claims that I don't have access to PM's.
